Product details

Molded tantalum in a 1206 footprint

Rated at 6.8 µF with ±20% tolerance and a 6.3 V voltage rating, the part fits low-voltage decoupling or bulk-storage roles on 3.3 V and 5 V rails where the derated voltage stays above 50 % of the rating. The 5 Ohm ESR (Equivalent Series Resistance) is the headline parametric — it defines how much ripple current the cap can handle before self-heating becomes a concern. For a 6.8 µF part at 6.3 V, this ESR is moderate; expect a ripple current capability in the tens of mA range. If your rail needs lower impedance at the switching frequency, a lower-ESR TAJ variant (same footprint, different suffix) is the swap.

Product status is Active.

Frequently asked questions

Can TAJA685M006RNJ be used as a replacement for another 6.8 µF tantalum?

It is a direct fit for any 6.8 µF, 6.3 V, 1206 (3216 Metric) tantalum with the same A case code. The key difference to check is ESR: this part has a 5 Ohm ESR. If the original cap had a lower ESR (e.g., 2 Ohm), the replacement will have higher ripple-induced heating and may not meet the same ripple current budget. Verify the derating in your circuit before substituting.
